Indicators and voltage indicators
Indicators and voltage indicators in our time are actively used by electricians. These devices are suitable for testing various microcircuits. Additionally, they are able to determine the voltage level in live parts. Thus, it is possible to engage in determining the performance of specific parts that are installed on electrical appliances.
To date, there are single-pole, two-pole and three-pole modifications, which are quite different in their parameters. You should also consider the features of models of specific manufacturers.
Single pole modifications
Single pole voltage indicator in our time is quite common. As a rule, models are used for testing microcircuits. However, they are also suitable for testing capacitors in power tools. On average, they are able to perceive electricity to 1 watt. However, there are more powerful devices on the market.
In the device model of this type are quite simple.Cases from them, as a rule, are made flat. When this tips are used contact. Mostly on the market you can find a single pole voltage indicator for two contacts. Resistors are used in many models of low power.
Bipolar modifications are characterized by a fast pulse. In this case, the contacts are mounted directly on the case. Some models of this type are available with displays. Thus, the voltage level can be monitored and fixed. To test the chips, these devices are ideal. It should also be borne in mind that they are able to serve power tools in excess of 2 kV. Washers in many models are installed contact type. When this resistors are used average power.
Three-pole modifications, as a rule, are used to work with transformers. In this case, amplifiers are of the chromatic type. In this case, the contacts of the models are connected to the device via wires. In this case, many devices are capable of working with equipment for 3 kV.There are special resistors for determining the voltage level.
Most often they are installed in the MLT series. Washers in many models can be found contact type. For tracking the readings of the device there are neon lamps. Directly transfer of current on the contacts is due to the trigger. Amplifiers in many models are installed operational type. However, wave modifications are also common.
Device models for 1 kV
Voltage gauges of this type are able to quite successfully participate in the testing of microcircuits. Amplifiers in such devices are installed, as a rule, of the synchronous type. In this case, the resistors are most often used double. The signal is directly transmitted through a trigger. Contactors in the system are used a variety of. It should also be noted that in some models are used convection resistors.
However, they are not very effective. In this case, the parameter of the output voltage of the device depends on the power of the thyristor. Thrust rings in the devices are installed under the spring. Additionally, rubber inserts are often used as a seal.
Modifications to 3 kV
Voltage gauges of this type are quite common today. They are ideal for testing electrical equipment. However, they cannot be used for low-power transformers. Additionally, it should be noted that they have a fairly large output voltage parameter. At the same time they are able to keep the load for a very long time. Triggers in them are used most often of the open type.
However, synchronous modifications are also found. The most common in our time is considered to be the model for two contacts. They are attached to the system through the washers. At the same time tips are connected with the boss. Thanks to this component, the signal is transmitted via a trigger. Amplifiers are used in models of different frequencies.
Features of 5 kV indicators
Voltage gauges of this type are mainly used by professionals. In the industrial sphere, they are used quite often. Devices with electric drives they can test. Additionally, it should be noted that they have a rather high current load parameter. On average, this indicator with some pointers can reach 30 A.Resistors in models are usually of a chromatic type.
In use, these devices are quite simple. The control panels for them most often the manufacturer provides an indicator type. Tips in shape can vary greatly. In this case, the signal processing speed depends solely on the power of the resistors. Additionally, it should be noted that in many indexes broadband amplifiers are installed. Due to this, the performance of devices is greatly enhanced. Triggers in many models apply the usual.
Model "UNN Combi"
The voltage indicator "UNN Combi" is actively used for testing electrical appliances. At the same time, it is also possible to check the performance of capacitors. The parameter of the current load of the presented device is at the level of 13 A. Additionally, it should be noted that it has two tips. Directly contacts are connected to the system through the washer.
In this case, the spring is installed above the screw. The trigger of the presented model uses a synchronous type. The resistors are set to average power.The output voltage parameter of this high voltage indicator is 1200 watts.
This low voltage indicator is quite popular today. The control system has a button type. At the same time the panel is used LED. Directly the output power of this model is at the level of 2 kV. There are two total contacts in the system. They are installed through a neon lamp.
The tips in the presented instance are available with a protective washer. Resistors are used in the MLN series. For high voltage transformers, these pointers are not suitable. It should also be borne in mind that the speed of processing the signal in a given instance is small.
